  • Abstract
    The longest common subsequence problem is to find a substring that is common to two given strings and is at least as long as any other such string. If m and n are the lengths of the two strings (m<2), we obtain O(log m) time parallel algorithm with mn processors and an O(log 2 n) time optimal parallel algorithm. Serial complexity on the decision tree model is Θ(mn)
